Water flows in a steel pipe (e = 0.00020 feet) at a flow Q = 12.5 cfs. The diameter of the pipe is D = 18 inches and the length of the pipe is L = 2,500 feet between section 1 and section 2. The elevation at section 1 is z = 100 feet above the datum. The elevation at section 2 is z2 = 75 feet above the datum. The temperature of the water is 70°F. The kinematic viscosity of the water is 1.06 x 10° ft/s. The pressure at section 1 is p1 = 90 psig (pounds per square inch gage). a) Determine the velocity v in feet per second (fps). b) Determine the Reynolds number Re. c) Classify the flow based on the Reynolds number Re. d) Determine the Darcy-Weisbach friction factor f. e) Determine the friction head loss hfäic in feet in the pipe between section 1 and section 2. f) Determine the pressure p2 in psiq at section 2.
